Sideloading

Much like sideloading during the initial install process, sideloading firmware upgrades or XDA apps can be done the same way.

Pre-requisites:

• Assumes TWRP Recovery is already installed and functional
• Fastboot (apt install fastboot on Debian)

First, connect the phone via USB

Make sure ADB is on:

adb devices

Now reboot, to recovery:

adb reboot bootloader

Once on the menu, navigate to Recovery

TWRP should load > Advanced > ADB Sideload

In your PC's CLI/terminal, reference the path where your .apk or flashable firmware zip is stored:

adb sideload /home/angela/Desktop/firmware.zip

Check the TWRP output to ensure it was a successful flash. If there are errors, they're typically pretty descriptive and will tell you if a dependency is not met.

If all is good, reboot back into the system.
